That means if you shell out $300 (again -- $300!) just so you can have a 4G BlackBerry, it will be outshone by a fancy dual-core phone in no time.

T-Mobile has plenty of excellent 4G phones that come at a reasonable $200 or less. To name a few: The T-Mobile G2x (free with two-year contract), Samsung Galaxy S 4G ($100 with two-year contract, and HTC Sensation 4G ($200 with two-year contract).
